In this study, the power of different classes of genetic markers in separating the two cod groups was investigated. The variation in thirteen genetic marker

A key factor in the effectiveness of a marine reserve-fishery system is the rate of exchange of biomass between reserve and fishery: if the rate of exchange is too low then the fishery is not viable, but if the rat

However, it has become clear that in addition to including these ‘structural’ elements of marine systems, management strategies should incorporate a consideration of the functional aspects of the ecosystems.
